'Bv 155V 1, W. Nr.360051 outside hangar 2 at the main Blohm und Voss facility at Finkenwerder,near Hamburg,Germany, late in december 1944.

he also mentions:
The Bv 155A featured wing radiators mounted above the wing and ws not built...
the first three prototypes, the Bv 155 V1 through V3, were allocated to the B-1 series, but only the first prototype was actually flown. The second prototype, the Bv 155 V2 was essentially 90 percent complete when captured by British forces, while the V3 was only 75 percent complete when the war ended...
The V2 was exhibited at RAE Farnborough in late 1945. The ultimate fate is unknown, but it has been suggested that the military offered the V2 to the British Aviation Industry for further testing and evaluation. Whether or not this offer was actually made, or accepted, is unknown.
Regarding the wing radiators, the port radiator was dedicated to cooling the oil for the engine, after cooler and intercooler. The starboard radiator served to cool the engine coolant.
